I'm not sure, you need the Mercedes description of the code.

Also, Mercedes stacks grounds on a common bolt / stud. If the point corrodes, circuits start to seek ground from each other causing all sorts of odd behavior.

I have a 97 E320 parts car that exhibits left fog light on , high beam indicator on , I message on the dash I can't recall and a trans that is in limp mode. Once, all of this went away at once the the trans shifted normally. I haven't looked very hard for the problem but I bet is is a common ground opening up
